Phung Thi Hung, chair of Hanoi-based Cat Tuong Technology and Import/Export Company, recently shocked people in her home country after consuming a bottle of what she called a very effective plant-based herbicide, to prove that it was safe for humans.

The unusual demonstration took place on April 21, during a workshop on controlling pests and protecting plants with biological methods in green agriculture. Phung Thi Hung was presenting her company’s latest products, a line of herbal herbicides that are very effective in preventing the growth of weeds while being completely safe for humans. To prove her claims, the female entrepreneur took a bottle of red fluid, which she said was one of her new herbicides, and gulped it down in front of the audience. She was joined in her demonstration by Dr Nguyen Dang Nghia, director of the Southern Research Center for Soil, Fertilizer and Environment, who also drank a whole bottle of the stuff. They are both reportedly still breathing.

A Dutch physical therapist turned inventor has spent 15 years developing a tailor-made pillow that he claims will solve any sleeping problems. At a price of $57,000, it better!

Created by Thijs van der Hilst, who is supposedly some sort of neck specialist, the world’s most expensive pillow is made of Mulberry silk, Egyptian cotton, non-toxic Dutch memory foam and 24-carat gold fabric, while its zipper is studded with four diamonds and a huge 22.5-carat sapphire. It sounds pretty expensive already, but it takes more than high-quality materials and jewelry to justify such an outrageous price tag for a pillow.

Coffee is more popular today than ever before, but many people abstain from consuming to much of it because it can really take a toll on their pearly whites. Well, thanks to the world’s first colorless coffee, you don’t have to worry about stained teeth anymore.

After getting tired of looking for a coffee drink that had the natural flavor they loved so much but didn’t stain their teeth, David and Adam Nagy, two Slovakian brothers who like strong coffee and their teeth white, decided to create it themselves. Called CLR CFF, their innovative drink is exactly what it sounds like – clear coffee, without the vowels.

If you’re looking for a way to shake off that nasty nail biting habit, this ain’t it. If anything, this prosecco-flavored nail varnish will only make it worse.

Prosecco Polish, “the world’s first edible prosecco flavored nail polish”, was created last month, by UK-based company Groupon, in celebration of Mother’s Day. It’s made with real Prosecco – a cheaper alternative to champagne – and apparently smells and tastes just like the popular Italian wine. The lick-able golden varnish not only makes your nails look pretty, but also places the flavor of prosecco literally at your fingertips to enjoy without fear of a hangover.

People are freaking out over a series of photos of people holding something censored by what looks like a photoshopped black circle. Only that’s really just an object painted with Vantablack, the world’s blackest black.

Developed by UK-based Surrey NanoSystems three years ago, Vantablack has been fascinating both scientists and artists ever since. This amazing pigment is composed of a series of microscopic vertical tubes that deflect light between them, essentially trapping it. Vantablack apparently absorbs 99.96 percent of light that hits it, making any three-dimensional object coated with it look like a black two-dimensional flat surface. So the object in these photos could literally be anything and you could never tell unless looking it from an angle that reveals its texture and depth.

If you’ve ever poured wine out of a glass bottle, you’re already familiar with that annoying yet inevitable stream of spillage on the side of the bottle. It’s been a bane of wine aficionados for centuries, but no more, thanks to this drip-proof wine bottle created by a biophysicist.

Humanity has come a long way in the last two centuries. We’ve found cures to deadly diseases, sent people into outer space and connected the world through the internet, but we still had to put up with the frustration of pouring wine. There’s no way to avoid spilling that delicious liquid when pouring it out of a classic glass bottle. Sommeliers know this and wrap a napkin around the neck of the bottle when they pour. But that just wasn’t a good enough solution for Daniel Perlman, a wine lover and biophysicist at Brandeis University. So he set out to find a cheap and effective fix to this centuries-old problem.

Cold hands are apparently a big problem for professional gamers and office workers, so a couple of young Danish entrepreneurs set out to find an efficient hand-warming solution. This ingenious keyboard heat lamp is the result of their work and research.

One night in May 2016, Emil Frølund and Mats Sørensen were playing Counter Strike in Emil’s basement. They were getting “owned” by their opponents, and like any real gamer, they had all sorts of excuses – bad teammates, slow internet connection, cold hands. And while they couldn’t do very much about the first two, that last one was definitely not out of their hands. That night, in a small basement, in Aarhus, Denmark, the Heatbuff keyboard lamp was born.

Don’t you just hate it when you have to take an important phone call and you’re surrounded by potential eavesdroppers? You either have to whisper or go outside to keep the conversation private, which is not exactly ideal.Now, a new gadget aims to fix this problem by muffling your voice and making you look like Bane in the process.

Hushme is a bizarre high-tech mask that blocks the sound of the wearer’s voice so that people nearby can’t hear what is being said. It connects to your phone via Bluetooth and comes with a pair of earbuds. When you get a private call, all you have to do is put the muzzle-like mask on and it will do the rest. The pair of thick cushy pads over your mouth do a good job of muffling your voice, but to ensure nothing gets through, Hushme also features external speakers that play a variety of sounds when you speak.

Fans of white T-shirts have long been looking to a solution to their transparency problem. No matter how thick the fabric is, you can almost always see through them, and the nipples, being slightly darker than the rest of the skin, are the most visible. Well, a Japanese company claims to have come up with an answer to this issue.

According to a 2013 Japanese study, 84 percent of women find looking at male nipples through their see-through white shirts disgusting, and men don’t like wearing transparent white clothes too much either, but they don’t really have too many options, especially when it comes to t-shirts. But now, a Japanese company called the the Seiso Shiro T Production Committee claims to have come up with the ultimate male nipple-concealing technology. Developed over a period of two years, using special Japanese stitching techniques and high quality, pesticide-free cotton from Japan, the USA, Uganda, and India, their new white t-shirts promise to make visible nipples a thing of the past.

Leave it to a man to come up with the dumbest solution to one of women’s most uncomfortable problems – menstruation. Daniel Dopps, a chiropractor from Kansas, USA, has obtained a patent for the “Mensez Adhesive Vaginal Lipstick”, essentially a glue stick that seals the vagina shut to contain menstrual flow. Yes, really!

“Mensez feminine lipstick is a natural patented compound of amino acids and oil in a lipstick applicator that is applied to the labia minora and causes them to cling together in a manner strong enough to retain menstrual fluid in the vestibule above the labia minora where the vaginal opening and urethra exit,” Dr. Dopps explains on his LinkedIn page. “The Mensez compound is instantly washed away with urine, which releases the menstrual fluid along with the urine into the toilet every time a woman urinates. No pads or tampons are needed. Safe, secure and clean.”

UK-based company The Unseen has recently revealed a revolutionary hair dye that can change between two colors whenever the temperature around the user fluctuates. This ingenious new product is called FIRE and despite being based on science, it looks like magic.

Within fashion circles, The Unseen founder Lauren Bowker is known as ‘The Alchemist’. It might sound like an exaggeration, but she and her team have indeed had some remarkable breakthroughs in design and fashion. The Unseen has patented color-changing technology that has allowed the company to create a variety of bespoke inks and coatings. These can in turn be used to create clothes and accessories that change color depending on certain factors, like temperature and humidity. But their latest creation, FIRE – a specially formulated hair dye that causes the hair to change color whenever the temperature fluctuates has been drawing the most attention.

A chemist, fashion designer and businesswoman, Lauren Bowker says that she came up with the idea for FIRE while watching a scene from the 90’s teen movie “The Craft”, more specifically a scene where Robin Tunney’s character goes from brunette to platinum blond by simply combing her fingers through her hair. “It was in that moment that the penny kind of dropped,” Lauren said. “I was like, ‘We could do that.'” And she did.

Designed to help frequent flyers bypass airport baggage queues, reduce baggage fees and virtually eliminate the risk of lost luggage, this modular Airport Jacket features 14 pockets and two detachable “pocket panels” that fit around 15 kilograms of luggage.

“With airlines beginning to charge for overhead carry-on baggage as well as severely restricting baggage allowances for the low fare economy traveler, my partner and I have designed a modular jacket that allows you to wear your laptop, tablet, two pairs of shoes, a pair of jeans, five t-shirts, a jumper and an SLR camera,” designer Claire Murphy explains. “It totals 14 deep pockets, including eight pockets at hip length, 11 pockets at three-quarter length and 14 pockets at full length. It includes two detachable pocket panels, and a carry-on size duffle bag.”

Claire and Benke Murphy came up with the idea for the Airport Jacket while traveling home with their newborn child. They had so much extra carry-on luggage, because of the baby, that the airline tried to charge them $140 for it, more than the cost of their tickets. So they had to clothes, gadget chargers, diapers and toys into their pockets, until they were just over the weight limit. They dodged the tax, but everything was sticking out of their pockets and it was a pretty uncomfortable plane ride. That’s when they decided that there was a massive need for a solution to this problem, and the idea for the Airport Jacket was born.

Goûte is a strange-looking spoon-like product that allegedly enhances the taste of certain foods by emulating the experience of licking your fingers. It was designed to replace regular spoons when enjoying creamy foods like yogurt, chocolate mouse or honey.

Goûte was created by Michel / Fabian, a design company that aims to rethink people’s relationship with food by designing eating utensils inspired by science and art. Founders Dr. Andreas Fabian, of Buckinghamshire New University, and Charles Michel, artist, food scientist and former Michelin-star chef, believe that conventional cutlery is only designed with functional purposes in mind, so they set out to create eating utensils that also “enrich the sensual pleasures of eating.” Goûte, for example, was designed to resemble a human finger, so using it to enjoy delicious creamy foods enhances their taste by recreating the experience of licking your fingers, without leaving them feeling sticky or greasy.

If you’re sick of waiting for summer to get a natural tan, it’s time you learned about TanRound, the world’s only apparel that lets you sunbathe all year round, even in the cold winter months.

Let’s face it, spray-on tans look nasty, and UV tanning beds are dangerous, but what’s a person to do when it’s too cold to go outside for good ol’ fashion sunbathing that not only makes you look good but replenishes your vitamin D reserves? Well, until not too long ago, we didn’t have too many options, but now there’s TanRound, an innovative line of apparel that allows wearers to sunbathe in cool temperatures down to -1 degrees Celsius. If you have no problem walking around in see-through plastic, it might be just what you’ve been looking for.

A Slovenian designer frustrated with constantly having to re-tuck his shirt into his pants has created a garter-belt-like shirt holder for men that keeps the wearer’s shirt tucked in at all times. The S-Holder is work around the thighs and attaches to the shirt via metal clips.

“I came up with the idea because I hated having to re-tuck my shirt all the time,” said 21-year-old Nik Vene, the inventor of S-Holder. “I was always having problems with this, so I did some market research and did not find anything that would help me. This inspired me to create something new, which was beautifully designed and made from high quality materials.”

Vene claims he spent six month turning his idea into a reality, and another five months creating an improved version. The S-Holder has adjustable side straps, new clips and comes in different color options. the young entrepreneur is so confident that there is a real demand for something that saves men the trouble of having to constantly re-tuck their shirts that he has recently started a crowdfunding campaign on Kickstarter.
